Engineers at the Tokyo Institute of Technology in Japan are building an odour recorder capable of doing recording a smell and playing it back later. "Simply point the gadget at a freshly baked cookie, for example, and it will analyse its odour and reproduce it for you using a host of non-toxic chemicals. The device could be used to improve online shopping by allowing you to sniff foods or fragrances before you buy [and] to add an extra dimension to virtual reality environments."-- New Scientist, Daily Mail, WMMNA
